Abstract

Measured values of the differential cross section for pion-nucleon charge exchange, π- → π0n, are presented at π- momenta of 148, 174, 188, 212, 238, 271, 298, and 323 MeV/c, a region dominated by the Δ(1232) resonance. Complete angular distributions were obtained using the Crystal Ball detector at the Alternating Gradient Synchrotron (AGS) at Brookhaven National Laboratory (BNL). Statistical uncertainties of the differential cross sections are typically 2-6%, exceptions being the results at the lowest momentum and at the most forward measurements at the five lowest momenta. We estimate the systematic uncertainties to be 3-6%.
